Change Fx from default Vestax Spin 2


I am using the Vestax Spin 2 together with Djay 2 on the Ipad.

I figured out how to change the main ‘Fx on’ button from the default ‘Echo’ to any other Fx by using the shift button + Fx on, but I can’t figure out how to change the default effect which can be accessed using shift + 1/8, 1/4 and 1/2.

Anyone knows how to accomplish that?

In addition, I bought the additional Fx packs from SugarBytes, but I would like to disable them on the Ipad (as I have to tap extremely often going through my effects on the controller (with shift + Fx on). Any ideas on how to do that?

Many thanks for your help.

p.s., I find it very strange that in the manual for the Spin 2, the above change for the main Fx button is not even described…
